ALVA T. UPTON, OF MOUNT VERNON, ILLINOIS.

TEMPEBING-VAT.

Application filed August 3, 1912, Serial No. 713,128.

I '0 all whom 2'25 may concern Be it known that I, ALVA T. UPTON, a citizen of the United States, residing at Mount Vernon, in the county of Jefferson and State of Illinois, have invented new and useful Tempering-Vat, of which the following is a specification.

The present invention relates to improvements in tempering vats, the primary object of the invention being the provision of a tempering vat adapted to be connected to and supported by an anvil, the same being especially adapted for use in connection with tempering the cut ends of a cold bit.

A further object of the present invention is the provision of a supporting device adapted to be connected to the anvil and to which is mounted a horizontally disposed and rotatable vat, said vat being provided with means to limit the introduction of the cutting edge of the bit therewithin and at the same time to properly support the bitduring the tempering thereof, said vat being further provided with means for r0- tating the same so that the bit may be automatically discharged from the vat to permit of the introduction of other bits and to render the manual removal of the tempered bit unnecessary.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a perspective view of an anvil with the present tempering vat disposed in operable relation thereto. Fig. 2 is a top plan view of the complete vat and support. Fig. 3 is a sectional View taken through the vat showing the adjacent portion of the support in operable relation thereto. Fig. 4 is a perspective View of the vat support per 86.

Referring to the drawings, the numeral 1 designates an inclined arm or brace of the supporting member which is provided with the downwardly bent terminal 2 which is threaded for the reception of the nut 3, said terminal being disposed for introduction into the anvil A, as clearly shown in F ig. 1, so that the vat carrying terminal or spindle Specification of Letters Patent.

at will be properly supported away from the anvil and in the position particularly as shown in Fig. 1. An arm 5 is connected to the spindle 4 and has an upright terminal 6 terminating in the curved end 7, this curved end 7 providing a means, as will presently appear, for automatically removing the tempered bit B from the circular Vat 8.

The vat 8, as clearly shown, is provided with the concentric tube 9 sealed at its upper end to provide an abutting means for the upper end of the spindle 4 and thus limit the downward movement of the vat 8 upon such spindle, the upper extreme end of the tube 9 being provided with the operating handle 10, whereby the vat 8 may be rotated to remove the tempered bit from the vat, due to the portion of the bit adjacent to the end 7 sliding thereupon and thus elevating the bit to permit of the falling thereof from the vat by gravity. In order to provide a means for limiting the introduction of the cutting edge of the bit B within the vat and at the same time assist in holding the bit in position during the tempering thereof, the uprights 11 are connected to and carried within the vat and support the ring 12 which is disposed below the upper rim of the vat and concentrically of the vat, the cutting edge of the bit B being introduced between the rim 8 of the vat and the ring 12 so that the upper end of the bit due to the overbalancing thereof will assist in holding the bit in such tempering position until the vat 8 is rotated by the handle 10 and the bit is disposed to ride upon the curved end 7 and thus automatically lie removed from the vat.

From the foregoing description, taken in connection with the drawings it is evident that a vat of this kind may be readily attached to any anvil and that the respective bits B after having their cutting edge sharpened with the device as set forth in applicants co-pending application heretofore mentioned, may be introduced with the cutting edge at a point diametrically opposite to that shown in Fig. 1 and that the opera tor may rotate the handle 10 to rotate the vat toward the ejecting end 7, and as the completed bits are disposed within the vats, one at a time, such ejecting end will eject the proper bit in succession due to the rotation of the vat 8 and after the bit has been placed within the tempering fluid the necessary period of time. With this form of vat a ready means is presented accessible to the anvil, thus permitting a single operator to cut a bit and place the same in tempering position, the bit being automatically ejectedby rotation of the handle and the rod 7.

What is claimed is:

1. A tempering apparatus, having a supporting member, a circular vat, rotatably mounted thereon, a ring mounted Within the vat below and concentrically of the rim thereof, said rim and ring co-acting to support a tool during tempering, means for rotating the vat, and an upstanding arm carried by the supporting member exteriorly of the vat and above the rim thereof and in the path to engage the tool during the rotation of the vat to eject tools.

2. A tempering apparatus, having a supporting member, for attachment to an anvil, said supporting member being provided With an upstanding cylindrical spindle, a

circular vat provided with a concentrically disposed tube rotatably mounted upon said spindle, means connected to said tube for rotating the vat, a ring mounted Within the vat below and concentrically of the rim of the vat, said rim and ring co-acting to support a tool during tempering, and an upstanding arm carried by the supporting member exterior of the vat, the upper end of said arm being disposed above the rim and in position to engage a tool at a time to eject the same during the rotation of the vat.

In testimony that I claim the foregoing as my own, I have hereto afliXed my signature in the presence of two Witnesses.

ALVA T. UPTON.
